l i P PER. RECEP-TACLE.

Be it known that I, CHARLES. FRANCIS JENKINS, citizen ,of the UnitedStates, residing at Washington, in the Districtof Columbia, haveinvented certain .new and useful Improvements. in Paper Receptacles, ofWhich the following is a specification, reference being had therein tothe accompanying drawing. l

Y In making boxes, usually of'paper, having interior and exteriortubular layers and provided with independently formed closures .oftendesirable to cut the inner layer or tube shorter than the other, so thatits ends may serve as shoulders or stops for the subsequently insertedends or closures. When, however, the inner layer'is very thin, the

An object of this invention is to avoid this evil without materialexpense, and at the end portions of the body, where a thinner sclosuremay safely be used. This is done by crimping and bending inward inroughly conical form the end portion of the In the accompanyingdrawings, Figure 1 is an axial section of a closed cylindrical boxembodying my invention; Fig. 2 is a plan or end view of the same boxwith the top cloeureremoved; Fig. 3 is a section similar to Fig. 1,showing a slight modifi-- cation. L

In these views,- A represents a cylindrical:

formed simultaneously, the method of forming not being here material.When the body has been formed, preferably plane, disks D are inserted inthe projecting end portions. of the outer tube and pressed'down againstthe edges of the inwardly bent poi-- tions of the inner .tube completingthe box. If the thin inner tube has considerable natural stiffness, thecorrugated portions when given a proper angle add very materially to thelateral stiffness of'the ends of thebox and therefore the end disks maybe made quite 'thin.

1 Boxes such as those thus far described are not suitable for liquids,but if the inner tube B, Fig. 3, has its end'faces made plane at E andparallel to. the end of the outer tube A, the closure D may be cc mentedto such plane face, and if the whole for liquids. As suggested in Fig.3, either novel construction may be used at one end only of the .boxwhile the other end of the compressed tube may be closed by otherdevices, such, for example, as the flanged disk F.

What I claim'is: h 3 l. A'bOX body made up of an. outer tube be given awaterproof coating, it will serve of uniform cross-section and an innertube closely fitting therein and having one end portion corrugated andbent inward at an oblique angle and its free 'marginat some. distancewithin the plane of the outer tubes end 2. A (paper box body consistingof an outer tube and a shorter inner tubeclosely fitting therein andhaving one end ortion carrled inward to form a conical rustu mterminating in a thin edge in position to meet a plane closure insertedin the end of the outer tube.
